摘要

摘要: 采用计算流体力学（CFD）方法对三段翼和MS-317后掠翼进行了积冰数值模拟研究，基于欧拉两相流理论，应用分区算法，对空气流场和水滴流场进行了数值求解，得到水滴收集率.求解3-D积冰模型得到积冰量.将MS-317的冰形计算结果与实验数据以及软件LEWICE3D的计算结果进行了对比.结果显示：三维积冰模型具有较好的精度，虽然预测的冰形与实验数据有一些差异，最大厚度方面，误差在13.1%以内，但是积冰的类型与体积和实验数据基本一致.

Abstract: Ice accretions on three-element airfoils and MS-317 swept wing were predicted by using CFD method. Based on Eulerian two phase flow theory, the governing equations for air and droplets were solved by using partition algorithm to obtain the water collection efficiency. The amount of ice accreted was calculated by solving the 3-D ice accretions model, and the predicted ice shape was compared with those of experimental and ice accretions software LEWICE3D results. The results show that the precision of the approach and algorithm is good. Although there are some discrepancies between the predicted ice shape and experimental ice shape, the error is less than 13.1% in terms of the maximum thickness, and the predicted ice shape is basically the same with the experiment data in terms of type and volume.
